X-rays as a Diagnostic Tool in Dentistry

November 20, 2013

X-rays are one of the best preventative tools we have in dentistry. As a visual exam only allows limited visibility of a tooth and is not able to tell the whole story. By using x-rays, dentists are able to assess the over-all health of a tooth, thereby saving time and money; preserving tooth structure and preventing painful situations.



Using X-rays to Diagnose

X-rays are useful in many ways. X-rays are used to diagnose many dental conditions including: decay between teeth, under restorations; periodontal disease; abscesses; infection of the bone or even tumors. Without x-rays, your dentist is not always able to detect these conditions. Letting any of these conditions continue without treatment can be problematic.


How often should you have x-rays

The length of time between x-rays depends greatly on your dental history and age. Depending on your dental history, it is recommended to have bitewing x-rays taken anywhere from every 6 months to every 24 months. For patients with a higher risk of cavities or periodontal disease shorter intervals between x-rays is recommended.


A shorter interval is also recommended for children as their jaw and teeth are still developing. The best way to determine how often you should have x-rays is to discuss it with your dentist. They will be able to explain how often you should have x-rays and why they recommend that specific interval for you.


X-ray Radiation

Many concerns about x-rays involve the radiation exposure for patients. Dental x-rays use minimal radiation and are targeted. We use a cone beam to target the small area around the specific tooth or teeth that need to be imaged. This limits the radiation to a small area. We use a lead apron and thyroid collar as an added precaution.


The radiation used for conventional dental x-rays is minimal – approximately 0.038 mSv for bitewings and 0.150 mSv for a full mouth series – just a fraction of medical x-rays. As an additional precaution, our Evanston dental office switched to digital x-rays 7 years ago to help decrease the radiation exposure for our patients. Digital x-rays use 70 to 80% less radiation than conventional x-rays.

 

X-rays are one of many tools that your dentist can use to help you achieve optimal oral health. X-rays are a great way to prevent pain and loss of your original tooth structure. Our Evanston dentists prefer to practice minimally invasive dentistry and believe that regularly scheduled x-rays are necessary in providing the best preventative dental care.

Pregnancy is a time of excitement, anticipation, and transformation. As your body adapts to nurture new life, your needs evolve—including your dental care. At Stephens Dentistry, we’re passionate about supporting expectant mothers through every stage of this journey. Understanding the connection between oral health and pregnancy is not just important for your smile, but for the wellbeing of both you and your baby.  How Pregnancy Impacts Oral Health Pregnancy brings about a surge in hormones, especially estrogen and progesterone, which can have a profound effect on your gums and teeth. Many women notice changes in their oral health during pregnancy, including increased sensitivity, swelling, or bleeding gums. These shifts aren't just uncomfortable—they can also signal conditions that need attention to safeguard your overall health. Pregnancy Gingivitis: What You Need to Know One of the most common dental issues during pregnancy is pregnancy gingivitis. According to the Centers for Disease Control and Prevention , up to 60–75% of pregnant women develop gingivitis, which is characterized by red, swollen, and bleeding gums. This occurs because hormonal changes heighten the body’s response to the bacteria in dental plaque. If left untreated, gingivitis can progress to periodontitis—a more serious gum infection that can cause tooth loss and has been linked to health risks beyond the mouth. Oral Health and Birth Outcomes The importance of oral health during pregnancy goes beyond comfort and aesthetics. Research has shown a significant link between maternal gum disease and adverse pregnancy outcomes, such as preterm birth and low birth weight. A systematic review published in the Journal of Dental Research found that women with periodontal disease may be more likely to deliver prematurely or have babies with low birth weights. Although more research is ongoing, the potential connection means that taking care of your gums and teeth is an essential part of prenatal health. Why Dental Care Shouldn’t Wait Some expectant mothers worry about dental treatments during pregnancy. The good news is that routine dental care—including cleanings and necessary treatments—are not only safe but recommended during pregnancy. The American College of Obstetricians and Gynecologists confirms that preventive dental work is important and can be performed safely, especially in the second trimester. Delaying care can allow small problems to become bigger ones, and untreated infections can pose a risk to both you and your baby. If you are planning to become pregnant, scheduling a dental checkup beforehand is an excellent way to get ahead of any issues. Practical Tips for Expectant Mothers Maintaining oral health during pregnancy doesn’t have to be complicated. Here are some tips to keep your smile healthy throughout your pregnancy: Brush and Floss Regularly: Aim to brush twice a day with fluoride toothpaste and floss daily. This helps remove plaque and reduce your risk of gingivitis. Eat a Balanced Diet: Focus on nutritious foods rich in calcium, vitamin D, and protein, which support both your oral and overall health. Manage Morning Sickness: If you experience vomiting, rinse your mouth with water or a fluoride mouthwash rather than brushing immediately afterward, as stomach acid can soften tooth enamel. Stay Hydrated: Drinking plenty of water helps wash away food particles and bacteria, and can also help combat dry mouth, which is common in pregnancy. Schedule Regular Dental Visits: Let your dental team know you are pregnant so they can tailor your care. At Stephens Dentistry, we take extra precautions to ensure your comfort and safety during each visit. Learn more about our preventive dental services . Recognizing When to Call Your Dentist While mild gum sensitivity is common, it’s important to reach out to your dentist if you notice persistent bleeding, swelling, or pain. These symptoms could indicate an infection that needs prompt attention. If you develop a dental emergency during pregnancy, don’t hesitate to contact your dentist—timely care is always the best choice for both you and your baby.
